COMBINATION WOODWORKING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 557,222, dated March 31, 1896.

Application filed April I, 1895. Serial No. 544,124. (No model.)

Ohio, have invented certain new and useful Improvements in Combination Voodworking-Machines, of which the following is a specification.

My invention relates to improvements in r o combination woodworking-machines. Its objects are, first, to provide and combine a number of different woodworking devices and tools in a single machine in such manner that each may be quickly and conveniently put into op- 1 5 eration an d without inconvenience on account of the other devices, and, second, in the improvement and simplification of various parts, including the operative table.

A represents the main driving-shaft, driven by means of treadle- A through connectingrods a, or by means of crank-arm A2, or by both together.

B represents a gearon shaft A, meshing with either gear C on shaft c or with gear .D on shaft cl, according to the speed required.

5o When gear B meshes with gear C, a high speed is transmitted to the operative shaft d through sprocket-wheels c fl and chain c2. Shaft d is adapted at its forward end to receive avariety of circular saws, gaining-heads, and similar revolving tools. It is also provided with a beveled gear e, which drives the friz- 1 zer-spindle E.

Gear C is much wider than gear B, and its hub is provided with a groove f to receive a metal strap secured to lever F, which is hinged to the cross-bar f on the frame G of the machine. The shaft c may thus be fed endwise by means of lever F. Suitable bits g are secured to this shaft outside the fly-wheel QQ which bits are used in connection with a suitable rest h to do heavy boring. Shaft cis journaled in brackets pivoted to the rear framepieces or legs G and secured to the front frame-pieces by means of bolts t passing through slotted openings in said brackets, by which means the shaft may be adjusted ver tically.

The table consists of a cast center plate I, provided at its four corners with arms or brackets e' 1l', latheways H H' secured upon the arms e', wooden side bars J, which are mortised into the way H and secured at their rear ends to brackets fi', a rear cross-bar J, and short bars 7c secured to the plate I and to the cross-bar J.

L represents side rails secured upon crossbars Z Z', fastened to the frame G. The table is pivoted at m to the side rails, so that the table, including the latheways, may be adjusted to the desired angle, as indicated in Fig. 3, where it is held by forked arms M and clamp-nuts INI', or it may be raised to a vertical position to give access to the parts beneath.

The forked arms M are of wedge or taper form in side elevation. This form is particularly advantageous in adjusting the height of the table, as when the nut M', Fig. 3, is slackencd the taper-arms M and table slip down slowly as the nut is turned, and when the right height is attained the nut is clamped tightly to hold the table in position.

The lathe head-stock R has two positionsone upon the ways II H and the other upon the ends of the cross-bars l Z' in the rear of the ways I-I H', as shown in Fig. 1. It is preferably placed in the latter position and pro- IOO vided with suitable bits g3 when used as a boring-spindle for light work. The lathemandrel is driven from sprocket-wheel c by substituting a longer chain for chain c2, which is used to drive shaft d.

The vertical adjustment of the table, together with the ways H H and other guideways, is of great utility, as it enables the operator to adjust the table to the varying heights required in using bit g3 orto regulate the depth of cut of the saws or gaining-heads on shaft cl.

The table as here constructed has many advantages over tables as heretofore constructed. The metal plate with its project ing arms forms a light, strong, and inde structible frame, by which the wooden bars and frame-pieces are firmly bound together and from which they may be readily detached and replaced. The table is free from all tendency to shrink or warp and is very economical in construction.

N represents ways for the saw or boringmachine guide O. Only one of these ways is shown upon the table; but others may be provided, if desired, upon dotted lines y 'y .2 2', Fig. 2. They are formed in the following manner: A groove n is cast in the face of the table with two or more pockets to receive Babbitt or similar metal boxes or supports ot' for the guide-rod. The guide is formed of the cross-arm o, secured by means of a slotted segment P to the guide-rod o, which is preferably formed of a piece of shafting and is provided at its forward end with a disk or plate o2, which serves to guide the end of the rod into the close-fitting boxes n and also prevents the end of the rod dropping down into the groove. The segment P is preferably seeured at three points of attachment to the rod o', p being the pivotal point and p clamping-bolts, in order to clamp the round rod firmly in the adjusted position. In Fig. 5 an adjustable stop is shown mounted upon the cross-bar o. It consists of a bracket composed of two pieces r o", swiveled at points q q and supporting a rod Q, one end of which is bent into a U form to present the end Q as a stop or gage where a number of pieces are to be cut Qr bored at the same distance from the end. This stop has a wide range of adjustment, which permits it to be used with material of widely-different proportions.

The latheways H H are designed also to serve as ways for the guide O, as shown in Fig. 1, the rod o resting between the ways, while the cross-arm serves to feed material to the boring-spindle, or the rod o may be clamped between the ways l-l H by means of the hand-wheel h' and the cross-arm used as a side guide for the circular saw or gaininghead.

Itis frequently desirable in frizzing long, large, or irregular pieces of work to hold the article vertically and have a horizontal cutter-head. This I provide in Figs. 11 and 12.

. 2 represents a frizZing-spindle supported between the head and tail stocks of the lathe. 3 represents a vertical rest for the work mounted and clamped upon the latheways.

ln Figs. 13 to 16 is represented a gaining cutter-head adapted to be used on shaft cl of my device. 4L represents knives secured between clampingplates 5. G represents grooves in the face of the clamping-plates, in which the edges of the knives a rest. The knives may thus be set at any angle desired by placing the edges of the knives on one side in, say, the outer groove and on the other side in ther-second or third groove from the edge, thereby giving the knives an easy draw cut instead of a scraping cut, which would result from setting the knives at right angles to the plates 5. 7 represents auxiliary knives which are set, one or more, upon each side and cutting a little in advance of the other knives. The working portion of these knives is angular in form. The vertical or shank portion of the blade travels in advance of the end of the blade, thereby giving the periph eral portion of the blade also a draw cut, preventing the shank of the blade from springing away from its work. The object of these knives is to cut across the grain and preserve a smooth edge while the knives l remove the bulk of the material.

Figs. 17, 18, and 19 illustrate a chuck for holding various bits commonly employed by woodworkers when my device is to be used as a boring-machine. 10 represents a sleeve screw-threaded at its rear end in order to attach it to the spindle. l1 12 represent the jaws employed for holding small bits. These jaws are provided with a flange 13 at the rear end, loosely fitting the bore of the sleeve, and at the forward end preferably with a taper-Han ge 14 slightly larger than the bore of the sleeve, while the intermediate portion of the jaws is of less diam eter than the boreof the sleeve. The jaws are provided with an angular socket 15 at the rear end to hold the shank of the bit and at the forward end with set-screws 1G to engage the stem of the bit. 17 represents a groove in the neck of one of the jaws, in which the set-screw 18 seats. 19 2O represent V-shaped lugs on one of the jaws, engaging corresponding grooves in the face of the opposite j aw, which prevents the displacement of the same.

The chuck is operated as follows: When it is desired to remove the bit, Fig. 17, the setscrew 18 is loosened and the jaws drawn forward, when the jaws will open at the forward end, due to the reduced circumference of the neck, and release the bit. The jaws are prevented from dropping out by the screw 18. lVhen it is desired to set a hollow auger in the chuck, the screw 18 is loosened until the jaws can be removed. The hollow auger, the shank of which registers with the bore of sleeve 10, is then inserted and clamped by set-screw 18.

S represents a scroll-saw hinged to the crossbar j and readily detachable therefrom. The
